Thanks D do you have some pictures? Do you tow anything w/the 265/75,s. My speedo is right on using Google map app. My rpm,s seem to be 400-450 off. It is reading higher than my Tech 2 scanner hooked up while driving. Does the alternator pulley also affect the rpm too? I do have 245/75 on...

Do you have a rear view? Do the tires stick out a bit? Thanks

I’m getting ready to get new tires on my 95’ Duelly. I would like the rear tire to stick out a little and fill the wheel well a little more. Not too much that it would rub. Would not be apposed to to spacers and what would the spacer width be. Also wouldn’t be apposed to a different size in the...

Not sure what you mean

Thanks guys , I will check it w/ the scanner. But I bet it is because I had a turbo master on my old motor. If so I still have it. I think I have the belt also for the vacuum delete. I do not tow anything. I’m running 410 axle gears. 4” open exhaust no muffler. And w/ the TDC Offset set at -114...

Thanks guys for all the help. I’ll double check the hose routing. I’m not running the turbo master. New stock set up. I do remember seeing the turbo vacuum pot open and closing when disconnecting vacuum. I do believe I have the vacuum lines on right. I’m using a Tech2 scanner. Will it give me...

Hi all I have a new GM 8 turbo on my new Optimizer. I can’t remember what my boost gauge readings were on my old stock one that came on the truck. I’m not sure this one’s working properly. When under a load going up hill no trailer I floor it and it jumps up then immediately drops to zero...

What’s the tallest tires can I put on my 95’ K3500 Dually with out rubbing ? Rear? Front? Thanks

You not the EPA are you lol😎

Hi All, I believe I got the ac working. I had too much oil in it, thanks dbrannon 79. I wanted to thank everybody for there help. I really enjoy coming on here and trying to diagnose problems w/ you guys😎. I’ll be posting on this site again w/ other issues I have. Thanks again.

Where did I leave off ? Oh yea put the fan shroud back on new discharge ac lines,new manifold gauges. Did my normal routine got one can in, took about 1 hour, got the compressor to come on with the low pressure switch plugged in, second can in took a long time also. The Freon these days come...

Thanks guys I knew you would have some ideas. The temp. of the lines coming from the condenser Definitely not the same Temps. Shouldn’t that line where I touched not be that hot. It’s after the orifice. Doesn’t the line temp. go down after the orifice? The orifice tube is black and white. The...

I forgot, the bottom large aluminum line coming from condenser ( the one that has the orfice in it) Is hot to the touch. The upper smaller line I can touch, it’s not cold either. Maybe a clue?

I got the new ac delco compressor on. Not making any noise but it not cooling. And high side gauge reading is not right. Pulled vacuum on system got about two cans in and the compressor is running off the low pressure switch. I’m going to try emptying and vacuum it and try too fill again. Any...

Yea I’m w/you the low side connecter is too close. I think because the vacuum pot is in the way. I’ll try rotating it more. I wish the rubber hose was a little longer. It’s so close.The silicone 4” tube it very flexible. When I slip it on it only pushes in a little. Has anybody put an in line...

Thanks guys fortunately I rebuilt the heater box while I had the dash out new doors and actuators. I guess that recirculate switch protects the lines and condenser? I have another issue. When I re installed my AC lines the suction line goes right in front of turbo not letting me put my 4”...

Thanks guys. I’m getting the comp. today and decided to replace the condenser and dryer. The parts store manager said Murray wouldn’t warranty the condenser because I bought the evaporator and dryer off Amazon and that he could give me those parts at his cost. The AC delco comp. he’s getting me...

Thanks for reaching out William. That is a good suggestion. I will even if it takes all day. It might not take that long mine only takes 2 1/2 cans 32oz. I can’t tell you how many times I’ve jump compressors to get the flow going with problems. I probably did that back in grease monkey days we...

Hey guys I did have the belt on the wrong side of the vacuum pump pulley. Sure making a lot of work for myself. I’m getting too old for this shit. All that chirping and screaming was probably the belt slipping, my bad🤯. I went back up to the parts house and there going to get me an AC Delco...

Thanks guys I’m at a loss on this one. The guys a the parts store are going to think I’m nuts. I can’t count on how many compressor replacements I’ve done. The four seasons paperwork said my truck 95’ ext.cab Denso comp. 32 oz a134 and 8 oz pag 150 oil. I agree the belt is sloppy I do remember...
